The character variation between two organisms or phenotypes are the starting point of gene analysis.  The discovery of Mendelian phenotype contributes a wide knowledge and understanding of the gene functions, gene regulations and the development of the biological mechanism.  There are various techniques that are effectively utilized to analyze the genetic constitution of an individual or population.  The Punnett Square can be used to predict the genotypes and phenotypes of offspring in a genetic cross. Punnett Squares are an effective and straightforward way to examine simple genetic crosses.  Unfortunately, it becomes cumbersome to count each square in finding the phenotypes and genotypes when there are more than two genes.  Punnett Square methods are time consuming when the inheritance of multiple characters is examined. 
Here I describe few methods that are used to calculate the precise mathematical ratios for phenotypic ratios.
